Description

Methanol burner

Technical Field

The utility model relates to a gas utensil accessory field especially relates to a methanol burner.

Background

The gas heating furnace is a boiler which heats water by using gas combustion so as to meet the requirement of heating of people, wherein the gas comprises natural gas, liquefied gas, city gas, coke oven gas, methane and the like. As a novel renewable energy source in recent years, compared with the fuel used by a fuel oil heating boiler, the methanol fuel is fuel oil and has the characteristics of high efficiency, safety, economy, cleanness and environmental protection. Is the key development direction of new fuel solvents in recent years, so the methanol heating stove is more and more favored by users and markets.

After the methanol heating furnace is powered on, the control system starts to detect the water level and the shell temperature of the boiler, the detection is normal, the boiler starts to start a methanol burner, methanol fuel oil is sprayed into a hearth of an inner container through a nozzle and then forms mist oil drops, the mist oil drops are mixed with air to burn rapidly and emit heat rapidly to heat water in a coil pipe arranged in the inner container, when the water temperature reaches a set temperature, the methanol burner stops heating, a hot water circulating pump is started, hot water in the coil pipe is conveyed to a heating pipeline system to circulate, and the heating purpose is realized through heat dissipation of a radiator (such as a radiator, a fan coil pipe water heating air conditioner, a central air conditioning unit and the like).

The core component of the methanol heating furnace is a methanol burner, the methanol burner mainly comprises a nozzle and an air feeder, and the methanol burner is used for spraying methanol fuel into a hearth of an inner container so that the methanol fuel forms a methanol atomizing torch; the latter has the function of supplying an appropriate amount of air to the oil droplets in the methanol atomizing torch. In actual use, the condition that oil gas formed by evaporation of atomized oil drops of the methanol combustor is anoxic easily in a high-temperature environment is found, incomplete combustion can occur, heating efficiency of the heating furnace can be directly affected, and the incompletely combusted methanol fuel can easily generate carbon monoxide and acidic substances, is volatile and has certain toxicity, and can harm users in human living environments. Therefore, how to enable the methanol oil gas to be better contacted and mixed with air at a high temperature state and enable the methanol oil gas to be more sufficiently combusted so as to reduce the harm of incomplete combustion to users in the living environment is a problem that the existing methanol heating furnace needs to be optimized urgently.

In addition, the existing methanol burner directly atomizes and sprays methanol fuel into the inner container hearth for combustion so as to heat the coil pipe arranged in the inner container hearth. However, in such a method, the flame is likely to be too concentrated, and the temperature of the dead space where the fuel is injected is lower than that of other parts of the furnace due to the absence of flame combustion, so that the temperature of the water in the coil pipe is likely to be uneven. The reason is that the direction, angle and coverage area of the nozzle cannot be fully distributed in the whole inner container hearth, so that dead angles are inevitably formed between the coil and the nozzle.
